Having a long work day is the newest risk factor that can increase a person's chance for developing heart disease, according to a British study.
Conducted by researchers at the University College London, the study found that English office workers who regularly worked 11-hour days or longer were 67 percent more likely to develop cardiovascular disease than those who worked seven or eight-hour days.
The study tracked more than 7,000 civil service employees between 1991 and 2004. Over that time, researchers found that about 2.7 percent of participants developed heart disease. While the study authors said they couldn't pinpoint an exact cause-and-effect relationship between lots of overtime and cardiovascular disease, lifestyle factors - such as the amount of time spent working - can significantly impact an individual's chance for developing the ailment.
"It could also be a wake-up call for people who overwork themselves, especially if they already have other risk factors," said Mika Kivimaki, the study's lead researcher.
A recent study found that sitting for long periods of time can be extremely harmful, and lead to illnesses that could raise health insurance rates. People who work long hours are likely to be sitting most of that time, which scientists found can increase the risk for heart disease, diabetes and early death even among people who exercise regularly.
